\ Marr- IMPROVE!) LIIII"J.I1`TG-fi.ll ACK.

. The Schedule referred to in these Letters Patent and making partof'the same.

\ To all whom it may concern Be it known that I, REUBEN M. REYNOLDS, ofOakville, in the county of Monroe, and State of Michigan, have inventeda new and valuable Improvement in Lifting-J ack; and do hereby declarethat *the follow ling is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part 4of this specicaton, and to 'the lettersand figures of reference marked thereon.

Figure 1, ofthe drawings, is a front View.

Figure 2 is a detail. My invention relates to lifting-jacks; and Y Itconsists in a novel arrangement of devices intended to serve efficientlyasV a means for lifting and sustaining carriages, while ,the process oflubricating the wbeelsis carried on, and for other similar uses.

A and B, of the drawings, represent two standards or posts, arrangedwith reference to, eachI other, upon an angle, as shown in tig. l. Theseposts are respectively held in place by the plates a, andl, on the frontpoints passes through and serves asa fulcrnm for the lever liereiiiafterdescribed.

K is the lifting-lever, pivoted upon one'of the points v of the stapleH, and also irmly attached to the block S, as hereinafter described.

S is a metallic block, cast with-a groovev adapted to'receive the headof lever K, and 'also with an ear, e, to receive and aid in operatingthe rod y. The cirv,cle'of said block, represented by a', ts closely tothe front side of standard A, and the samepoint of the staple thatpasses through thelever K, passes also through the centre of the circle,and serves as a pivot for4 its movements.

It is a strong rod, bent at each end, so -as to form right angles withthe body, one'ofwbichbent ends enters the ear e, while the other isoperated at willin theopenings d of the lifting-post'.

To operate my device, one end of the rod R is placed in' an, opening, d,and the lever is, pressed down.- Vhen the lever is forced downward tosuch a point that the rod R becomes perpendicular with the liftingpost,or a little bey-ond that point, the Weight lifted is sustainedVautomatically by the jack itself, and requires neither hand or weightupon the lever. p

What I claim asmy invention, and desire to secure by-Letters Patent, is-'The 'lifting-jack herein described, having posts A,

B, and D, staple H, lever K, block S, and bent rod- R, constructed andarranged to operate substantially as specified. In testimony that I.claim the above, I have hereunto subscribed my name, inthe presence ot'two witnesses.
